Chloe is holding milk in her mouth after a feed. She does it every time now. She will feed fine, I burp her successfully, sit her upright for a bit then she either goes to sleep or plays. What ever she does she has a mouthful of milk which she will either spit or dribble out sometime later- she has just spat it everywhere after her 7am feed 2 hours later. Its definitely not sick, I've even started tipping her on her side to get it out before I put her down but she manages to hold some back. Any ideas why she would do this? And is she the only one!?
